DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. When appropriate, the same reference numbers are used throughout the drawings to refer to the same or like parts.

FIG. 1 a flow chart of an exemplary method 100 for adaptively adjusting a user interface of an intelligent terminal device. Method 100 may include a series of steps. Some steps may be optional.

In step S101, a posture parameter of the intelligent terminal device may be acquired. The posture parameter may include a yaw angle a of the intelligent terminal device. In another example, the posture parameter may include a roll angle y of the intelligent terminal device. In a further example, the posture parameter may include both the yaw angle α and the roll angle γ of the intelligent terminal device. Both the yaw angle α and the roll angle γ can be detected by a direction sensor of the intelligent terminal device. Acquisition of the posture parameter may be performed when the user is using the intelligent terminal device, such as when the user is making a phone call when the intelligent terminal device is a cell phone. The posture parameter may be acquired multiple times. For example, the posture parameter may be acquired a predetermined times, such as 100 times. In addition, whether the intelligent terminal device is being used to make a call can be determined by reading call status data using a Software Development Kit (SDK) interface of the operating system of the intelligent terminal device.

FIG. 2 shows an intelligent terminal device in a three-axial space. For ease of description, it is assumed that extending directions of the width, length, and thickness of the intelligent terminal device correspond to the X-axis, Y-axis, and Z-axis shown in FIG. 2, respectively. An initial posture of the intelligent terminal device can be defined when: the positive direction of the X-axis points to the right of the intelligent terminal device (e.g., to the east), the positive direction of the Y-axis points to the head or the upper portion of the intelligent terminal device (e.g., to the north), and the positive direction of the Z-axis is perpendicular to the plane of the screen of the intelligent terminal device (e.g., the horizontal plane) and points up (e.g., to the sky). Starting from the initial posture, the yaw angle can be defined as a rotation angle by which the intelligent terminal device rotates horizontally around the Z-axis relative to the initial posture (assume that the clockwise rotation is positive), where the value of the yaw angle can range from 0° to 360°. For example, when the Y-axis points to the north, the yaw angle can be defined as 0°, and when the Y-axis points to the south, the yaw angle can be defined as 180°. Similarly, when the Y-axis points to the east, the yaw angle can be defined as 90°, and when the Y-axis points to the west, the yaw angle can be defined as 270°.

A pitch angle can be defined as a rotation angle by which the intelligent terminal device rotates around the X-axis up and down relative to the initial posture (assume that the rotation of the head or upper portion of the intelligent terminal device towards the positive direction of the Z-axis is positive). The value of the pitch angle may range from −180° to 180°.

The roll angle can be defined as a rotation angle by which the intelligent terminal device rotates around the Y-axis left and right relative to the initial posture (assume that the rotation of the screen side towards the positive direction of the X-axis is positive, and the rotation of the screen side towards the negative direction of the X-axis is negative). The value of the roll angle may range from −90° to 90°.

In some embodiments, the yaw angle, the pitch angle, and the roll angle can all be detected by a direction sensor of the intelligent terminal device. Posture parameters may be collected when the user is in a normal standing or sitting position. When the user is not in the normal standing or sitting position (e.g., when the user is lying down or making calls with an headphone on), posture parameter may not be collected.

In step S102, a processor device of the intelligent terminal device may determine the dominant hand information of the user according to the posture parameter. In some embodiments, the posture parameter may include the yaw angle a of the intelligent terminal device. If the yaw angle α is in a range of 0°<α<90°, the processor device may determine that the user of the intelligent terminal device uses his/her right hand to hold the intelligent terminal device, as shown on the right side of FIG. 3. On the other hand, if the yaw angle a is in a range of 270°<α<360°, the processor device may determine that the user of the intelligent terminal device uses his/her left hand to hold the intelligent terminal device, as shown on the left side of FIG. 3. The determination may be made while the user is making a call while holding the intelligent terminal device with either his/her right or left hand.

In some embodiments, the posture parameter may include the roll angle γ of the intelligent terminal device. If the roll angle γ is in a range of −90°<γ<0°, the processor device may determine that the user of the intelligent terminal uses his/her left hand to hold the intelligent terminal device. On the other hand, if the roll angle γ is in a range of 0°<γ<90°, the processor device may determine that the user of the intelligent terminal uses his/her right hand to hold the intelligent terminal device. Similar to the determination process based on the yaw angle, the determination process based on the roll angle may be performed while the user is making a call while holding the intelligent terminal device with either his/her right or left hand.

Regardless of whether the yaw angle α or the roll angle γ is used to determine the left/right hand, such determination process may be made multiple times. For example, the direction sensor may detect a plurality of posture parameters during a series of events. For each acquired posture parameter, the processor device may determine whether the user uses the right or left hand to hold the intelligent terminal device. Assume that a total number of N posture parameters are acquired, for each of the N posture parameters, a determination process is carried out to determine whether the user uses his/her left or right hand to hold the intelligent terminal device. There may be L number of times that the processor determines that left hand is used and R number of times that the processor determines that right hand is used.

If a ratio of L/N, indicating that the number of times that left hand is used over the total number of times the posture parameter is acquired, is greater than a preset threshold (e.g., 80%), or if L>R, the processor device may determine that the dominant hand of the user of the intelligent terminal device is the left hand.

Similarly, If a ratio of R/N, indicating that the number of times that right hand is used over the total number of times the posture parameter is acquired, is greater than a preset threshold (e.g., 80%), or if R>L, the processor device may determine that the dominant hand of the user of the intelligent terminal device is the right hand.

In Step S103, the processor device may adaptively adjust the user interface of the intelligent terminal device based on the dominant hand information of the user. For example, if it is determined that the dominant hand of the user is the left hand, the user interface of the intelligent terminal device may be adjusted from a right-hand mode (e.g., when the right-hand mode is the default setting) to a left-hand mode. If it is determined that the dominant hand of the user is the right hand, it may not be necessary to make an adjustment if the right-hand mode is the default setting. In this way, for each user, a personalized user interface conforming to the dominant hand of the user may be provided, making it more convenient for any user, especially the left-handers, to use the intelligent terminal device. User experience may be improved.

In some embodiments, the user interface of the intelligent terminal device may be by default in the right-hand mode. A left-hand mode may be provided by mirroring (e.g., left-right mirroring) the display settings of the right-hand mode. Both the right-hand mode and the left-hand mode may be provided as configuration files in advance. The right-hand mode or the left-hand mode can be selected according to the result of the determination process described above. As shown in FIGS. 4A and 4B, display positions of a same UI control element (e.g., the black blocks 401 shown in FIGS. 4A and 4B) on the screen of the intelligent terminal device in the two different modes may be symmetric with respect to the central vertical axis of the screen.

In some embodiments, the user interface of the intelligent terminal device may be a user interface of an APP of the intelligent terminal. In this case, once the mode is adjusted, even after the APP is restarted, the APP may remember the mode preference and display the adjusted user interface. In some embodiments, the user interface of the intelligent terminal device may be a user interface of an operating system of the intelligent terminal device. In this case, once the mode is adjusted, even after system reboot, the system may remember the mode preference and display the adjusted user interface.

An exemplary code illustrating the disclosed method is provided as follow, in which yaw angle α is used in the determination of the dominant hand.
